Y 15 Claims. (Cl. 20L-53) The present invention relates, in general to windows and, in particular, to-windows of the type in which the window is rotatable about a vertical axis as well as tiltable about a horizontal axis. Y

Prior art windows, of the type to which .the present invention relates, are provided with a locking lever at the side of the window opposite the side thereof which is rotatable about a vertical axis.

For operating such windows, the locking `lever acts on push-pull rods which are usually mounted in the intersection of a vertical pivot, -`about which the window rotates, and of a horizontal pivot, about which the window tilts. The lever must be set either for turning or tilting of the window, after which the desired window motion can be effected by loosening the locking lever. However, this type of window operation is somewhat cumbersome, and has therfurther disadvantage that improper manipulation of the locking lever, for example, might cause the window flap or sash to fall and be damaged. Safety devices have been provided to eliminatethis hazard but, of necessity, they require additional parts and thus increase the cost.

Therefore, it is an object of the present invention to provide means aiming at the elimination ofA the disadvantages of the prior art. i

Another object of the present invention is to provide means ensuring independent movement, on the one hand, of the locking lever and its associated parts and, on the other hand, of the push-pull rods so as to superimpose the two movements upon each other. y

Another object of the present invention is to provide means conducive to a very ethcacious construction where only one part has to be operated either to'turn the window about la vertical axis Vor to tilt it about a horizontal axis.

A further object is to provide means affording a generally simplified window construction of the type to which the present invention relates.

A still further object is to provide means facilitating the prevention of improper manipulation of `the window.

Pursuant to one important feature of the present invention, the disadvantages of the prior art are eliminated by the provision that the push-pull rods in the window fittings are connected with locking elements and the locking lever, with its associated parts, is movable independently of the push-pull rods in such manner that the two movements are superimposed.

According to another feature of the invention, a longitudinally displaceable' member or casing is mounted at the side of thewindow which'has the lock. The casing is operatively connected to the push-pull rods which act on locking elements. The locking lever is preferably mounted for free rotation on the longitudinallymovable housing. The movements of the push-pull rods are transmitted to the movable casing so that the locking lever and its locking elements move' in a corresponding manner. In thisvmanner,l it is possible to open the locks, which 3,004,304 Patented Oct. 17, 1961 Y Therefore, it is necessary only to actuate the locking lever to effect rotary movement of the window flap.

In the above described arrangement, the actuating or locking lever is vertically reciprocated when the pushpull rods are moved so that a corresponding large opening must be provided in the window frame.

=In order to obviate such movement of the actuating lever, it can be mounted on the window so that it is freely rotatable but fixed against displacement. In this arrangement a pawl engages the longitudinally displaceable casing during movement of the latter and operatively connects the latter with the locking elements. When the push-pull rods are reciprocated, there is no longitudinal displacement of the actuating or locking lever, but only a rotary movement thereof, which is desirable since the opening for the locking lever can be made relatively small. The longitudinally displaceable casing can, in addition, constitute a side ybearing for a locking bar movable by the locking lever, so that the necessity `for an additional part is obviated. The pawl, which-is provided for coupling the locking bar with the displaceable casing, is preferably supported with its lower end freely rotatable on the movable casing, and is provided at its upper end with two oppositely directed lugs, one of which is adapted to engage in a complementary recess in the locking bar, and the other is rounded off so that, in the lower position of the casing, it engages a cut-out in the casing guide. This results in a particularly simple and safe construction.

The movable housing is preferably T -shaped in crosssection. The transverse portion or head `serves as a guide for the locking bar and the longitudinal portion receives the locking lever, its driving element and a connecting rod. In order to facilitate sliding of the casing, the latter is mounted in a guide having a U-shapedcrosssection which is inserted in the window. As previously indicated, the present invention provides a simple protection against improper manipulation of the window by limiting the major motion of the locking elements by suitable stops. In the rotary setting or condition of the window ap, the locking elements of the locking lever are open and, according to the present feature, in a limited position so that no movement of the pull rods is possible.

In order to limit the tilting of the window ilap, an arm can be used in addition to bars arranged on the upper horizontal edge of the flap.4 According to another feature of the invention this arm is mounted forfree rotation on the movable casing, and its Vfree end glides in a guide arranged on the window frame, said arm being disengaged from the guide inthe rest position of the ap.

Pursuant to a particular embodiment, a longitudinally displaceable and pivotally movable locking bar is secured on the side of the window having the locking lever. Movement of the locking bar is effected', on one hand', by the'push-pull rods and, on the other hand, by the locking lever, the locking bar cooperating with the locking elements securedto the other window part which can be locked and unlocked by lifting and turning. In

3 T this embodiment, one bar can be eliminated since the locking bar and the connecting bar are combined in one part. The rotary movement of the locking bar is derived preferably from the push-pull rods and the longitudinal motion in this case is effected by the locking lever. The locking bar is preferably provided at its lower end with a longitudinally displaceable but non-rotary sleeve which is equipped on its circumference with a toothed segment which engages recesses provi-ded in horizontal push-pull rods. The freelyrotatable locking lever, secured on the window, abuts the locking bar between two annular lugs xed on the locking bar. In order to minimizeparts, the locking bar is formed, at its lower end, as an angle hinge pin-and cooperates with a complementary tting.

For special uses, provision is made for a modified form wherein longitudinal movement of the locking bar is derived from push-pull rods, and rotary motion is effected by the locking lever. The locking bar is providedat its lower end with a rotary but non-displaceable sleeve which is connected with the horizontal push-pull bar by an angle lever pivoted on the window. The locking lever is mounted for free rotary movement on the displaceable but non-rotary sleeve and the latter is secured between the arms of a forked bearing mounted on the window. In order to mount an additional bar, another freely rotatable but non-displaceable sleeve is mountedon the locking bar which receives, in free rotation, the arm cooperation with a guide. In this embodimenL-the locking bar can be provided with one or more locking hooks which engage L-shaped recesses in parts secured on the other window part.

These and otherV objects of the invention will become further apparent from the following detailed description, reference being made to ther accompanying drawings showing preferred embodiments of the invention.

Referring now to FIGS. 1 through 6 in detail, there is shown a window 100 pursuant to the present invention. Said window comprises a iixed window frame 4` on which there is hung a movable ap 1 which comprises a: sash 101 provided with a window pane 102. The window Hap or movable window member'l4 is mounted both for rotary or turning movement about -a vertical axis by a pivot 2 and for tilting movement abouty a horizontal axis by a pivot 3. The window is shown in its closed condition in FIG. 1. Pivot 2 is receivableY in" a complementary lock element 5, in which it is freely rotatable, and constitutes therewith the lock 5A.

Similarly, pivot 3 is receivable in a complementary lock element 18, in which it is freely rotatable, and constitutes therewith the lock 18A. In order to open and close locks 5A and 18A, provision is made for the vertically reciprocable push-pull Frod 6 and the horizontally reciprocable push-pull rod 7v mounted in sash 101. Rod 6 mounts pivot t2 to move the latter into and out of complementary lock partiS and rod 7 mounts pivot 3 to move the latterinto'and'out of complementary lock part 18. Rods 6 and 7 are coupled by the pivoted angle lever 6A. A manually op'erablelever 8, mounted on sash 101 and secured to rod 6, eifects' reciprocation of both rods in conventional manner. A locking lever 9 is mounted on the sash on the yside thereof opposite the side on which lever 8 is mounted. Lever 9 actuates a locking bar 10 that cooperateslwith locks 11 vertically spaced on the windo'wframe 4. 'Lever 9 is provided with a rotary shaft 12 which is mounted in a vertically displaceable casing 13, as best shown in FIG. 2. Shaft 12, which is freely rotatable in the casing13, mounts a toothed gear segment 14 which lengages in complementary recesses 1S provided on the locking bar 10. IIt will be understood that turning oflocking lever 9 will elect', rotary movements of shaft 12 and segment 14 to raise and lower bar 10 to open or close locks 11.

Movable casing 13 is coupled by connecting rod 16 and the pivoted angle lever 17 with the horizontal pushpull rod 7. Consequently, it will be apparent that actuation of lever 8 will also effect vertical reciprocation of casing 13. FIG. 2 illustratesk the window in its closed condition.- The casing 13 and the locking bar 10 are both in their lowermost positions sojthat the locks-11 are closed. Lock'lSA is open and lock 5A is closed, as shown in FIG. Y1, so that the window flap 1 can be turned and rotated about pivot 2,- which in the illustrated condition, constitutes a vertical axis of rot-ation. Thisv can be accomplished -by ai corresponding rotation of the locking lever 9 to the rotated position thereof shown in FIG. 5 wherein the manual lever 9 has been turned down from the position thereof Vin-F'IG. 1, so that segment 14 has moved locking 'oar 10 up to open locks 11. Movement of segmenty 14 to itsv upper and lower positions are limited by detents 14A and 14B; respectively. In order to open the window to the tilted position thereof, the flap 1 must rst be in the closed position thereof shown in FIG. 1. Thereafter, lever 8 is operated or turned to `open-lock 5A and to close locklSA. The resultant movement of ro'd 7 is transmitted to connecting rod 16 so that casing 13 and locking bar 10 are pushed up to release locks 11.

Consequently, it will be ,apparent that lever 9 is operated in order to effect rotary movement of window memb er,102 about a vertical axis and lever 8 is operated to effect tiltingLmovement of said member about a horizontal axis, whereby' to simplify the operation ofv said window member.

Stops 19limit movements `of th'e locking bar 10. When lockingbar 10Yis in its uppermost position by operation of locking lever 9, asy shown in FIG. 5, actuation of lever 8 is no longer possible since the locking bar isA fixed in its position and the friction of segment 14 relative to bar 10 is very large. 'l l.

FIGS. 6A and 6B illustrate another lfeature of the invention. An a'rrn20is mounted, as at 20A, for free rotation on movable cvasing v13. The armV is provided at its free end121 with a bolt 22 which rides in a guide member 23. mounted on window frame 4. In the tilted open position shown in FIG. 6A, upward movement of boltf22V is limited by the top of theY guidemernber 23. When the window memberl is returned to its closed posi- 76 tion frorrrits tilted open position, bolt- 22 is in the position As best shawn in FIG. 3, the casing 13.15 -r-shaped in cross-section. The hollod bend or transverse portion 26 serves as a guide for the locking barl 1|),v while the shaft 12 of the locking lever, with the segment 14 and the connecting rod 16, is supported .by the longitudinal portion 27 In order to facilitate sliding of the casing 13, the latter is mounted in a U-shaped guide 28 inserted in the wooden frame or sash 101.

, In the embodiment illustrated in FIGS. 1-6, oper-ation of lever 8 is accompanied by a longitudinal movement of locking lever 9. This requires a relatively large recess 13A in sash 101. FIG. 7 illustrates an embodiment in which longitudinal movement of lever 9 is obviated. Shaft 12 of lever 9 in FIG. 7 is -not secured to casing 13 but is secured to sash lilla.` Locking bar 51, which is cut oi at both top and bottom, is mounted above connecting rod 16 and is provided with ratchet teeth 52 which engage gear segment 14. Londitudinally displaceable casing 53 has a slightly different form than corresponding casing 13 and, in addition, has a freely rotatable pawl 54. Pawl 54 has two lugs 55 and 56. Lugi55 engages recess 57 in bar 51 and lug 56 protrudes, in the lowermostposition of the casing, into ya outout 58 in guide 28.

As soon as casing 53, and consequently pawl 54, are moved up by motion of connecting rod 16, pawl 54 turns to theleft, as shown by arrow 54A, due to cooperation of itsrounded lug 56 and cutout 58, so that its lug 5S engages in recess 57 of bar 51 to establish a rigid connection between the bar Iand the connecting rod so that the bar is also moved upwardly. This carries along the segment 14 causing the latter, and consequently shaft 12 and lever 9 to rotate but not to be moved upwardly. However, if the lever 9 andthe shaft 12 are moved, while in `the position thereof `shown in FIG. 7, lug 55 does not engage in recess 57 and bar 51 is moved without any change in the position of rod 16.

`In the present embodiment bar 51 can also be provided With a locking journal 59 which cooperates in con` ventional manner with a'complementary tting (not illustrated). In addition, arm 20 can be connected to the casing S3.V

There are several possibilities of superposing the two motions of the individual locking elements. Instead of two longitudinally movable bars, as shown in FIGS. 1-7, it is possible to use two rotary bars.

In addition, it is also possible to arrange the two bars so that one is pivoted while the other is longitudinally displaceable. This results in `another embodiment dependingo'n whether the rotary bar constitutes a locking bar or a connecting bar. In two additional embodiments represented in the'drawings, the functions of the connecting and locking bars are combined and only one bar is provided to performv both unctions simultaneously. y

Referring now to lFIG. 8 in detail, locking bar 29 is connected with a sleeve 36 so that the locking bar can be displaced longitudinally therein but not rotated. Sleeve 30 is secured on window member 1 in a manner not illustrated. The horizontal push-pull rod 7 has recessed 31 atits free end. As shown in IFIG. 9, said recesses are engaged `by, `a toothed gearv segment 32 mounted at the circumference of sleeve 30. Movements of push-pull rods 6 and 7 are ythus transmitted, as a rotary motion, to locking `Lifting motion is achieved by locking lever 33 pivotally mounted on windowl member 1. Lever 33 is pivoted, as

at 34,'.and abuts two annular vertically spaced lugs 35,"

' the-,other side of said assembly, means for locking saidv to move bar 29 upwardly. This disengages pin 36'from fitting 37. A fitting 3S is mounted on frame 4 above the upper end of the locking bar. The tting has an L-shaped recess 39. A hook-shaped part 40, at the upper end of bar 29, extends behind a lug 41, provided on part 38, in the lowermost position of bar 29. Upon upward movement of bar 29, hook 40 moves upwardly beyond lug 41 into the upper portion 42 of cutout 39 whereby to release bar 29 so that the window member can be rotated.

To tilt the window, lever 8 is moved whereupon the bar 29 is rotated about its own axis by the push-pull rod 7 so that hook 40 can move out of recess 39. Hinge pin 36 remains in hinge fitting 37 since this permits a tilting motion.

FIG. 11 illustrates another embodiment of the invention wherein` longitudinal motion of locking bar 43 is effected by push-pull rod 7. Bar 43 is rotatable but not axially displaceable within a sleeve 44. vSleeve 44, in turn, is hinged by an angle lever 4S, pivoted on window memberlasat 45A, onrod 7. I

As best seen in FIG. 13, a forked bearing 46 is secured onjwindow member 1. Bearing 46 receives between its arms 47-47 a sleeve 48 which is connected with locking bar 43 for displacement but not for rotation thereby. Locking lever 49 is hinged, as at 49A, freely rotating in sleeve 48.

Bar 43 is again provided with a hook-shaped element 40 ,which engages an L-shaped recess 39 of fitting 3 8. The method of operation is substantially the same as in FIG. 8. The only difference is in the derivation of the individual movements. In FIG.- l1, the longitudinal motion'of bar 43 is obtained by rod ,7 and rotary motion by turning lever 49after its release from catch 49B, and thereby turning sleeve 48 on bar 43.

In orderto provide an additional arm 50 in this embodiment, another sleeve 60 is mounted on bar 43, freely,

rotatable but nondisplaceable, to carry armv 50. VArm 50 cooperates with -guide 23 in the same` manner as described in connection with'FIG. 6. Y j

In the embodiment illustrated in FIG. l, the various moving parts are mounted onrwindow member 1while the fixed parts are mounted on window frame 4.

It is within the scope of the present vinvention to3utilize the opposite arrangement wherein the movable parts are mounted on frame 4 and the xed parts on member 1. It is also possible to mount, selectively, moving and xed parts both on the frame and on the window member. The securement of the locking lever 9 on -frame 4 provides a particularly simple embodiment. The `connecting rod 16 illustrated in FIG. 1 can also be extended atjthe top and can even be conducted about the whole frame. It is possible also to couple the connecting rod with the push-pull rod 7 so that a closed rod drive is obtained. p

Various changes and modications may be made without departing Afrom the'spirit and scope of the present invention and it is intended that such obvious changes4 and modifications be embraced by the annexed claims.'
